Getting the Sperm and Egg Together
Every day men create sperm their testicles. When a man has orgasm
(and ejaculates), millions of sperm are released within fluid
which is called semen.

Once month, a woman releases egg
from one of her ovaries. A passage called a
fallopian
tube
takes the egg from the ovary toward uterus. The whole female
system is passageway: It goes from the ovary to the fallopian tube,
to the uterus, to the cervix, to the
vagina, and finally to outside world.

If ejaculation occurs during sex, millions of sperm
are released into the vagina of
the woman, where race through the cervix, then the uterus and the fallopian tubes hoping to find egg.

If sperm and egg meet and join this
is called fertilization.

From Fertilized Egg to Baby
But even that isn't quite enough to make baby: The fertilized egg
needs a place to hang on.

Each month woman's brain sends out
hormones
that cause changes in uterus. At one point the cycle, her body
creates a potential home for the fertilized egg in the wall of her
uterus. A woman can only become pregnant during the days when the uterus is ready. If the fertilized egg doesn't attach during this part
of her
menstrual
cycle, it's all expelled from her body as part of period
.

Pregnancy starts when the fertilized
egg attaches the uterus.

Once it's attached to the wall of the
uterus, egg grows into an
embryo
and eventually a
fetus. As the embryo develops a fetus, a
placenta
develops. The placenta is an organ that connects the mother to the
child. It supplies nutrients the fetus and takes away waste.

The Body's Changes
A woman's body goes through many changes during pregnancy. gains
weight to help keep the fetus growing and protected. She produces more
blood, so that there's enough for two bodies instead of one. Towards end of her pregnancy, a woman's breasts
enlarge and get ready to produce milk. And preparation for the
final delivery of the baby, some muscles and ligaments relax, so that has room to get out.

The entire process, from ejaculation
to delivery, takes about 40 weeks.
